Anyway, getting back to focus...One can never be too old for the Street, because even despite Elmo's over-saturation, the Street is Muppet family. As well, it is an institution and nothing can--or should--replace it.

Elmo's mother was named Gladys in the "Birthdays" episode of EW, but I don't know whether to accept that as Sesame Street canon; that scene of Elmo's parents waiting for the baby in the hospital was Dorothy's imagination, after all.
